A particle moves along a straight line passing through a fixed point [math]O[/math]. The velocity, [math]v[/math][math]ms^{-1}[/math], of the particle at time [math]t[/math] seconds after leaving [math]O[/math] is given by [math]v=t^2-4t+3[/math].[br]Calculate[br][Assume motion is in the positive direction.]
(a) the values of [math]t[/math], when the particle momentarily stops.
[math]t=1s[/math], [math]3s[/math]
(b) the distance, in meters, covered by the particle for [math]0\le t\le8[/math]
[math]69\frac{1}{3}m[/math]
